Pan/Tilt Issues
Tilt continues to move past center during calibration, and...
"TILT: no sensor" is displayed in Status Log and TLT sub-code is red
Details: During initial Pan/Tilt calibration at power-up, Tilt will line up between the yoke legs and Pan will rotate looking for its
mechanical stop. If Tilt continues to move past center, it is an indication that the COT sensor has failed or is unplugged from
the Pan/Tilt Controller PCB. In addition, the Status Log will display error "TILT: no sensor" and the TLT sub-code will be red.
Solution: Re-connect Pan/Tilt COT Sensor Cable.
Solution: Replace Pan/Tilt COT Sensor...
PAN sub-code is red and Status Log contains one or more Pan-related error codes, and/or...
TLT sub-code is red and Status Log contains one or more Tilt-related error codes
Details: Upon power-up, the Pan/Tilt Controller PCB performs a calibration procedure that the Pan and Tilt must pass before
allowing control of these two functions. The Tilt moves to a position between the two yoke legs and stops. The Pan rotates the
yoke until it contacts the pan stop and reverses directions for half a turn then stops. The Status screen will show the PAN and
TILT sub-codes in green if they pass. If the Pan/Tilt Controller PCB is faulty, or if either mechanism fails, the sub-codes will
appear on the Status screen in red and there will be one or more entries in the Status Log containing an error message.
Procedure: Remove the Pan-Side Yoke Cover (
) and verify all connections to the Controller PCB are secure. If all
connections are good, and the Pan and/or Tilt still fail, replace the Pan/Tilt Controller PCB with a tested "known-good" PCB. If
the failures continue, follow up on the error codes to isolate the source of the failure. If the failures stop, replace the Pan/Tilt
Controller PCB.
Solution: Replace Pan/Tilt Controller PCB...
Pan motor does not stop running after calibration, or...
"Pan Aux Encoder Fail" is displayed in Status Log and PAN sub-code is red
Details: Upon power-up, the Pan moves all the way around to the pan stop and stops moving, then rotates 180 degrees and
stops again. If it reaches the first stop and the pan motor continues to run, the Pan Drive Assembly has most likely failed. If
upon power-up, the Pan calibrates and the Status Log displays "Pan Aux Encoder Fail," the Pan Drive Assembly’s auxiliary
encoder has failed.
Procedure: Verify that all Pan and Tilt cables are properly connected to the Pan/Tilt Control PCB (
). It could save time by
installing a known-good Pan/Tilt Control PCB to eliminate that component as a cause of the malfunction. If installing a good
Pan/Tilt Control PCB does not fix the problem, the Pan Drive Assembly should be replaced.
Solution: Replace Pan Drive Assembly...
Tilt continues to move after it has reached center position between yoke legs during calibration, or...
"Tilt Aux Encoder Fail" is displayed in Status Log and TLT sub-code is red
Details: Upon power-up, the Tilt will move to a position between the yoke legs and stop moving. If the Tilt continues to move
after it has reached the center position between the yoke legs, the Tilt Drive Assembly has most likely failed. If upon power-up,
the Tilt calibrates and the Status Log displays "Tilt Aux Encoder Fail," the Tilt Drive Assembly’s auxiliary encoder has failed.
Procedure: Verify that all Pan and Tilt cables are properly connected to the Pan/Tilt Control PCB (
). It could save time by
installing a known-good Pan/Tilt Control PCB to eliminate that component as a cause of the malfunction. If installing a good
Pan/Tilt Control PCB does not fix the problem, the Tilt Drive Assembly should be replaced.
Solution: Replace Tilt Drive Assembly...
Pan Drive or Tilt Drive Mechanism has no power
Details: A 3 Amp Timed (Slo-Blow) Fuse protects the two drivers for the Pan/Tilt Controller PCB.
Procedure: If power is lost to either the Pan Drive or Tilt Drive Mechanisms, visibly check drivers for any damage. Verify all
cables are properly installed. Replace the Pan/Tilt Controller PCB if any damage is detected. Inspect the cables to ensure they
are not damaged or shorted. Replace any blown fuses and recalibrate the fixture.
Solution: Replace Pan/Tilt Controller PCB...
Solution: Replace 3A Fuse...
